CAPSULE-CUTTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 268,961, dated December 12, 1882 Application filed April 13, .1882. (No model.)

To all whom it may concern Be it known that I, HARRISON H. TAYLOR, of Detroit, in the county of Wayne and State ofMichigan, have invented new and useful Improvementsin Capsule-Cutting Machines; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings,-

which form a part of this specification. m The nature of this invention relates to certain new and useful improvements in the construction of machines for cutting off gelatine capsules; and the invention consists, first, in the mode of cutting 0E the capsules by means of laterally-moving knives, in combination with loose forming-pins; and, second, in the peculiar construction and arrangement of parts, all as more fully hereinafter set forth.

Figure l is a front or end elevation of my machine. Fig. 2 is a vertical central crosssection'. Fig. 3 is a side elevation. Fig. 4 is a top plan, with part of the follower broken away so as to disclose portions of the underlying parts. Fig. 5 is a detached perspective of a portion of a knife secured to its shaft.

In the accompanying drawings, A represents the bed'pla-te, to which is attached the vertical plate-standard B, the outer ends, a, of which form guides for the follower G. This follower consists of the vertical portion 1) and the horizontal and overhanging part c. To the underside of the latter the mold-plate D is removably secured in any convenient manner. The mold-plate D carries, as usual, a series of 5 pins, E,upon which the gelatinecapsules were previously formed in the usual manner. For the proper operation of my machine, I use pins which areloosely set into the mold-plate, so as to be able to rotate upon their axis, and the pins E shown in the drawings are of that desoription.

On topof the bed A, andjournaled in bearin gs cl (1 at each end thereof, are the shafts F F These shafts are provided at the front end of the machine with the intermeshing and like pinions, G G, while their rear ends are provided with the circular racks H H. Atthe rear end of the machine, and journaledinproper bearin gs e 6 upon the bed, are the cross-shafts I 1. Upon the outer ends ofthese shafts are the two intermeshing pinions K K. The shaft I is provided upon one end with a crank-handle, L, by means of which it can be rotated, and

it has also secured upon it the pinions l M", which engage respectively with the racks H H The shaft I has secured upon it the double pinion M M which engages'with the racks H H N N are two levers, fnlcrumed at ffto the standard B. Their outer ends are provided with pins gg, which engage with the under side of the followernea-r the outer ends thereof. The follower-plate G is free to slide up or down upon the standard B, and its whole weight therefore rests upon the'pins g, imparting to the levers N a tendency to rise at their inner ends.

O'is a sliding block held in the vertical slot P in the standard, and it is provided with the I projecting ledge i, and a pin, it, which latter engages in the slots 70 in the inner ends of the levers N N.

Q, is another sliding block held in the slot P of the standard, and it is provided with the ears I l, between which the cam-lever It is ful- 7 5 crumed.

S is a stop-screw entering from the top ofthe standard, with its lower end impinging upon the sliding block Q.

Each of the four shafts F F has secured to, So it, in any convenient manner, theknife-blade T. Its upper end is bent at right angles, and is properly grooved to form a cutting-edge. Parallel slits m subdivide the blade T into individual knives U, whose euttingedge is a 8 little longer than one-halfot' the circumference of the former-pins E. I

V is a lever attached to the front end of the shaft F and W is a segment provided with notches an, with which the lever V is adapted 9o toengage.

In practice the mold-plate D, upon whose pins E the gelatine capsules are formed, is secured to the under side of the overhanging part c of the follower, and to allow this to be done withoutinterfering with the knives U thelatter have to be in the position shown in dotted lines in Fig. 1, which position is obtained by en gaging the lever V into the lower notch 12 of the segment W. After the mold-plate is put 10o 7 in its prescribed position and locked therein Fig. 4, where the pins are shown in dotted outlines. Now, the crank L is taken hold of by the operator and turned from its position shown in Fig. stand in dotted outlines in Fig. 3 to the position shown in Fig. 3 in full lines. This movement, by meansof the different pinions and engaging racks described, pushes the shafts F and F one way and the shafts F F the opposite way, and the pins E, being loose in their sockets, will therefore be rotated upon their axis by the movement of the cuttingedges ofthe knives U, this rotation being made of sufficient duration to allow the knives to cut the capsules entirely around the pins.

, The operator new seizes the cam-lever It,

which is in the position shown in Fig. 1, and raises it up into the position shown in Fig. 2, and brings it back again to its old position. This movement drops the follower U a little distance, allowing the knives U to push and break oft the separated portions of the capsules, thereby freeing the latter from the cuttings. The operator now engages the lever V again into the lower notch, n, which movement diverges the knives from the pins and allows the mold-plate to be withdrawn. As the whole weightof the follower O is supported upon the ends of the levers N, the sliding blocks 0 and Q have a tendency to rise in the slot P of the standard, and the setscrew will therefore adjust the follower O to any desired position.

Although I prefer to rotate the pins E by moving the knives on both sides of the pins, it is obvious that one set of knives might be stationary and the other moved laterally a proper length to cut around the pins.

What I claim as my invention is 1. The method of cutting off gelatine cap- 7 sules by moving the'knife or knives laterally, the former-pins being set loosely in the mold plate and adapted to be rotated upon their axis by the movement of the knife or knives, substantially as set forth.

2. In a cutting-off machine for gelatine capsules, the cam-lever R, in combination with the slidingblocksO and Q and levers N, for raising the mold-carrying frame, substantially as and for the purposes specified.

3. In a cutting-off machine, a series of parallel shafts provided with intermeshing pinions for simultaneously rotating the same in alternating directions, and, in combination therewith, the knit'e-blades T, secured thereto and actuated thereby, substantially as set forth.

4. In a capsule-cutting machine, the combination of the devices for laterally moving the shafts F F, consisting of the shafts I 1, pinionsKK, and pinions M M, the latter engaging with the racks H H, constructed, arranged, and operating substantially as and for the purposes specified.
